Patent CA-2035707-A1 (CA)
Inventor: CROWLEY MARK
IPC: B65C3/02
Filed: 1991-02-05
Abstract: ABSTRACT           A tool which is adapted to removably engage a rolled, semi-rigid, plastic label, retaining the label in an open orientation to facilitate placement of the label on a pipe.  In the preffered embodiment, the tool includes an elongated handle connected to and extending outwardly from the bottom side of a base plate.   A plurality of support posts attach to and extend outwardly from the top side of the base plate, and support a pair of label racks proximate the free ends of the support posts.  Each of the label  racks  has  at  least  one  label  engaging  flange disposed  on  one  side  thereof.   The  label  racks  are disposed apart from one another on the support posts in an opposed,  inwardly facing manner.   The  label engaging flanges are thus disposed in an opposed, inwardly facing surface to releaseably engage opposite edges of a rolled plastic label and releaseably retain the rolled plastic label in an opened configuration for placement on the pipe.   This tool is typically disposed on an extension section or bar to place labels on pipes which are a distance from the user.

Abstract: NON-CRUSHING WELLHEAD                        ABSTRACT An improved slip suspension wellhead is disclosed for suspending a selected tubular member inside another without crushing.  An inclined support surface is provided with a second support surface which may contact a portion of the slip assembly to halt axial movement of the slips relative to the wellhead body.  The second support surface is placed along the inclined support surface at a pre-selected point in order to stop the radial movement of the slip gripping faces before the inner slip diameter is compressed below the sum of the drift diameter plus two times the maximum wall thickness for the selected tubular member.  Therefore, the improved wellhead may utilize  slips having  substantially reduced axial length without danger of crushing the tubular member.

Abstract: ABSTRACT            A network-field interface, termed an NFI (12) is intended for digitally interfacing at least one host computer (14) on a network (10) to at least one field device (11). The network (10) operates with a predetermined communications protocol including READ and WRITE services. The NFI comp-rises I/O ports (22,24)  for connection to the field de-vices,  a  modem  (55,Fig.5)  to  facilitate  communication between the network and the interface, a CPU (51,Fig.5), volatile and non-volatile memory (52,53,Fig.5) accessible to  both  the  modem  and  the  CPU,  and  program  modules resident in the memory. The program modules are executable by the CPU to map the READ and WRITE services of  the network onto the NFI's I/O ports.  In this way the host computer is able to READ and WRITE directly to the I/O ports through the modem.            (FIGS. 1,2,5)

Title: Process and system for removing dissolved and undissolved contaminants from water
Inventor: PAQUIN JEAN
IPC: B01D15/00
Filed: 1991-05-28
Abstract: ABSTRACT OF THE DISCLOSURE         Treatment of water containing contaminants, by  removing  substantially  all  of  the  contaminants therefrom   the   contaminants   forming   emulsions, colloids and fine droplets in the water phase.   The process  comprises  passing  the  contaminated  water through  a  pre-filter  capable  of  retaining  coarse and/or  suspended  materials,    and   allowing   the pre-filtered water to exit therefrom.    In a second step,   the  pre-filtered water  is passed  through a hydrophobic oleophilic absorbent partitioning filter which has  been impregnated with a  substance which strongly partitions the contaminants in favor of the impregnating     substance,       thereby     removing substantially  all  the  contaminants  that  can  be removed  by  absorption.     In  a  third  step,   the remaining contaminants are removed through adsorptive post-filtration  employing  suitable  media,   one  of which   may   be   the   non-impregnated  hydrophobic oleophilic  fiber medium which  may  subsequently  be used  to  constitute  the  impregnated  partitioning filter.   Other typical examples of adsorbent filter media  include  activated  charcoal  and  diatomaceous materials.     A  system  including  a  combination  of pre-filter,  partitioning filter and post-filter is also disclosed.

A device moves the lead-in roll  from  a  first  to  a  second  location with the first location  being  in close  proximity to the press roll such that  when  the tail box is connected to a source of vacuum, the  tail  is  drawn  away  from the press roll onto a dryer felt extending around the lead-in roll.  The second location is  spaced  from  the  press  roll such that an open draw is established  between the press roll and the lead-in roll.  A tail  guide  is movable from a first to a second disposition with  the  first  disposition  being  such that the guide is retracted   from   contact   with   the  tail.   The  second disposition  is such that the tail guide physically contacts the  tail  for  urging  the  tail  laterally relative to the lead-in  roll  into  engagement with a threading rope system which extends around the lead-in roll.

Title: Arrangement for processing sensor signals
Inventor: SCHNEIDER GEORG
IPC: G01D5/24
Filed: 1990-12-11
Abstract: The arrangement serves for the processing of sensor signals which are furnished by a capacitive sensor which includes a measuring capacitor having a measuring capacitance influenceable by a physical measured quantity to be determined and at least one reference capacitor having a reference capacitance influenceable in another manner and furnishing a measuring effect dependent on the measuring capacitance and the reference capacitance. The arrangement comprises a signal processing circuit which operates by the principle of quantized charge transport by means of switch-capacitor structures and charge balancing at least in time average and which receives the sensor signals representing the measuring effect and furnishes an output signal corresponding to the measuring effect. The first electrodes of the capacitors of the sensor are at a fixed potential and their second electrodes are connectable for performing the charge transport to the first input of an input operational amplifier, the second input of which lies at a reference potential. The reverse charging of the capacitors of the sensor necessary for forming the transported charge packets is effected by switching over the reference potential of the input operational amplifier. This permits a one-sided fixed binding of the sensor capacitors to any desired potential.

Title: Polygon fragmentation method of distortion correction in computer image generating systems
Inventor: KELLY WILLIAM A
IPC: G06T3/00
Filed: 1992-03-12
Abstract: A method for distortion correction of computer-generated textured images maps vertices and texture coefficients from viewer space to projector space, so that environmental objects are pre-distorted upon the projection raster in order to appear in their proper form and perspective when the raster is projected onto a curved surface in viewer space, and viewed therefrom. Distortion correction is carried out by utilizing a piecewise-linear approximation for smoothly, continuously and closely approximating the required pre-curvature. The viewing space raster is subdivided into a number of triangles, within each of which a linear approximation is applied to the image mapping: the raster faces are first subdivided along the lines of a rectangular grid and the face fragments falling within each rectangle are then subdivided along the grid diagonal. This produces face fragments which are small enough so that a linear approximation provides an accurate transformation of each fragment. Distortion maps, typically computed off line and stored in a database memory, are utilized to project the edges and texture modulation gradients from view space back into projector space, so that the edges and texture patterns can now be matched at intersections of adjacent triangles, in a manner to be substantially devoid of any abrupt changes, and thus be properly pre-distorted.
